Clean Working Conditions
CAUTION:
CAUTION! Whenever working on fuel supply and fuel injection systems, carefully observe the following six rules of cleanliness
NOTE:
- Thoroughly clean fuel system line and hose connections and the surrounding area before disconnecting.
- Place removed components on a clean surface and cover. Use plastic sheeting or paper.
- Do not use fluffy rags that could leave lint!
- Carefully cover over or seal any components that have been opened if repairs are not carried out immediately.
- Install only clean parts: Do not remove replacement parts from the packaging until immediately before they are to be installed. Do not use parts that have been stored without packaging (e.g. in toolboxes, etc.).
- When the fuel system is opened: Avoid working with compressed air whenever possible. Avoid moving the vehicle if possible.
- Make sure that no Diesel fuel runs onto coolant hoses. Affected hoses must be cleaned immediately. Contaminated hoses must be replaced.
